'Interstellar glaciers': NASA's SPHEREx maps vast galactic ice regions
NASA's SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer) mission has mapped interstellar ice at an unprecedented scale. Covering regions in our Milky Way galaxy more than ...

Astronomers crack a decades-old mystery, catching gas morphing into planet-building disks around newborn stars
An international team led by Dr. Indrani Das of Academia Sinica Institute of Astronomy and Astrophysics (ASIAA) has shown, for the first time, how infalling gas from star-forming cores gradually transitions into planet-forming ...

Dark matter could explain the earliest supermassive black holes
A growing mystery in astronomy is the presence of gargantuan black holes—some weighing as much as a billion suns—existing less than a billion years after the Big Bang. According to the standard theory of black hole formation, ...

A 3D map of 47 million galaxies is redefining our view of the universe
For the last five years, the Dark Energy Spectroscopic Instrument (DESI) has been systematically scanning the night sky. Today marks the completion of its first map, which is the largest high-resolution 3D map of the universe ...

Astronomers reveal always-changing multi-planet system
Astronomers at The University of New Mexico have published new research confirming three bodies orbiting the dynamic exoplanet system TOI-201. They include a super-Earth (TOI-201 d), a warm Jupiter (TOI-201 b), and a brown ...

The universe's most powerful telescope
SN 2025mkn is a Type II supernova and it wasn't supposed to be visible at all. The violent death of a massive star that had exhausted its nuclear fuel and collapsed under its own gravity sits at a redshift of 1.371. That ...

A monster black hole appeared first, then its galaxy began to grow around it
Using observations gathered by the James Webb Space Telescope (JWST), an international team of astronomers have revealed that one supermassive black hole in the early universe must have formed before a galaxy developed around ...
JWST spots methane on a giant exoplanet, but its star may be distorting the signal
Using the James Webb Space Telescope (JWST), astronomers from Johns Hopkins University (JHU) and elsewhere have observed a giant exoplanet known as HATS-75 b. Results of the new observations, published April 8 on the arXiv ...
Catching distant gamma-ray explosions with precisely aligned X-ray optics
Gamma-ray bursts (GRBs) rank among the most powerful explosions in the universe, releasing immense energy in intense flashes of gamma rays. The most distant GRBs originate from the era when the first stars and galaxies formed. ...

Not so dark with Alena Tensor: Math framework could explain dark matter without invisible particles
Alena Tensor is a relatively new mathematical approach that allows for arbitrary curving and straightening of analyzed spacetimes. As it turns out, generalizing this model to all known fields and fully describing matter, ...
Webb redefines the dividing line between planets and stars
Planets, like those in our solar system, form in a bottom-up process where small bits of rock and ice clump together and grow larger over time. But the heftier the planet, the harder it is to explain its formation that way.

Shredded stars reveal how black holes ignite trillion-sun flares
Supermassive black holes are among the most enigmatic objects in the universe. They typically weigh millions or even billions of times the mass of the sun and sit at the centers of most large galaxies. At the heart of the ...

Torsion balances set strongest direct limits yet on ultralight dark matter
Dark matter is believed to make up a large fraction of the matter in the universe, yet its true nature remains unknown. Most past experiments have focused on heavier dark matter candidates, while much lighter dark matter, ...

Could dark matter be made of black holes from a different universe?
New research suggests that relic black holes from before the big bang may still shape galaxies today. These black holes could explain dark matter, one of the biggest unsolved questions in cosmology.
